The object of the invention is to provide improvements in ink wellsofthe desk stand type, and more particularly in that class which makesits own ink as is required from water, as representative of any suitablesolvent, anda soluble ink tablet-or the like.

Another object of the invention is to provide specifically a desk standhaving either one or a plurality of ink wells, each of which has aclosure for the discharge orifice, a removable, solvent reservoir, andan auxiliary chamber to receive solvent from said reservoir, andconnected with the ink well by a relatively small bore or channel.

A further object is to provide the orilic ofeach well with a closure,comprising a gravity actuated member such as a ball or disc, adapted tobe moved from said orifice by and as a penis inserted into said well,and which member is operative upon the withdrawal of the pen to returnunder the'influence of gravity to close said orifice.

Still another' object is to provide in a stand a well adapted to receivea soluble ink-making pellet, a chamber spaced from said well butconnected therewith by a relatively small bore, and a removablereservoir carried by said stand above and in air-tight union with saidchamber, and having a discharge aperture communicating with saidchamber, said reservoir, if desired, having a removable closure providedwith an aperture for the ingress of air, and to admit atmosphericpressure to the surface of fluid within said reservoir.

And a still further object is to provide in said stand a drawer,`havingcompartments for holding soluble ink-making pellets, stamps or the like,spare pen points, etc., said stand being provided with removable meanscooperating with said drawer and operative to limit the extent ofmovement of the latter.

'With these and other objects in mind, the present invention comprisesfurther details of construction and operation which will be fullybrought out Vin the following description when read in conjunction withthe accompanying drawings, in which Fig. 1 is a top plan view of `oneembodiment of the in vention; lFig. 2 isa front elevation of the same;Fig. 3 is a front-to-rear vertical section taken through one oftheink-making and dispensing sections of the device; and Fig. 4 is aperspective view of the preferred form of drawer used in the device. s

Referring to the drawings, a desk stand is illustrated as formed'of anysuitable material, such as glass, bakelite, or other suitable substance,and comprises a body portion l, in whichare located as many inl:- makingunits'as may be desired, though there are here illustrated Vbut two suchunits adapted to make ink of different colors, if desired, such forinstance as red and blue-black, as

represented by the inlaid color discs 2 and 3 in the front ef said bodymember and in alignment with the respective wells 4. y

A single unit will be described as illustrative of any desir-ed number,and this Lunit, be-

sides the well just mentioned, comprises also an auxiliary chamber 5,preferably spaced to the rear of said well, but connected thereto Yby arelatively small bore or channel 6. The

well 4 is provided with a discharge aperture 7, spanned by any suitableform of removable closure, but described.

This closure comprises a body portion 8, having an upper forwardly anddownwardly slanting surface 9, through which extends downwardly a bore10, its lower portion being surrounded by a ilangell, which supports inany suitable manner a gasket 12 to provide an air tight connectionbetween said closure and the sidesV of said aperture and also topreferably by the closureherein .yieldingly resist the tilting orremoval of said closure from said aperture.

This closuremember is also provided with a radially inwardly directedflange 18, at the upper limit of the lbore 10, whi'chnormallysupports aball or other gravity-actuated member or the like 14. From the rear andlaterally opposite sides of the closure member 8 rises a wall 15 ofsubstantially U-shaped cross section, the rearward portion of the area Yinclosed by said walls being lcovered by a top 16, and the forward edgeportions of the side walls being brought slightly towards each otheratl? to prevent the accidental removal of the ball la tl'ie'reloy.` lThe rearmost" i portion of the U-shaped wall 15 is piovided with asuitable projection 18, which serves to stop the rearward movement ofthe ball 14 when displaced by the insertion of a pen through the bore10, to prevent said ball if wet with inl; from adhering by capillaryaction and the drying of the ink to the rear poition of said Llc-shapedwall.

The rear portion of the stand 1 surrounding and concentric with thechamber is provided with an annular internally threaded cutout portion19, adapted to lreceive the depending externally threaded Aflange2O`Hoi`a *i cylindrical reservoir, closure 21, which is provided kwith ahorizontally extending bottom wall 22,V pierced by one or more orifices'A 23. The upper' free end portion of said closure is externally threadedat 24j to removably receive the internally threaded cylin'drical'portion25 of any suitably shaped cover 26 for saidreservoir, having'an' orificeZ27 for lthe ingress of air, and also to admit atmospheric pressure vatall times uponthe surfaceof a fluid within said reservoir. y

The reservoir closure 21 extends radially outwardly beyond the threadedsurface' of the dependingange 2O to'provide a shoulder 28, and betweenthis shoulderand the ad jacent upper surface or" the stand '1surrounding the'cut'out portion 19 is vpositioned ,a coinpressiblegasket 29, the purpose lof whichk is toinsure an air-tightunion'be't'ween said stand and reservoir closure above said auxiliarychamber.

An interesting'feature inthe operation of this device is that'whenassembled as'sliowu in Fig. 8, butywith the cover 26'removed, water orother fluid` may be poured into the reservoir closure 21, whence itflows through the orifice 23 into the auxiliary chamber 5 and throughthe bore 6 'and into lthe well 4.

Remembering that there is an' air-tight connection between the closure21 and" the stand 1 to provide an air tra-p within the chamber 5, as thefluid continues to flow downwardly through the orice 2.3, the fluidlevel within the chamber 5 remains at the upper level of the bore G,althoughY the fluid level witliin'thc well 4 continues to rise andremain substantially constantly at' the under surface of the flange 3()through' which extends the discharge aperture 7. When the fluid levelwithin the well has risenjto the point indicated, further reserve fluidis f placed withinV the reservoir closure 21 and the cover placed inthepositionV shown. During the subsequent operation' of the device awriting pen, orV an eye dropper or the like for filling a fountain pen,is inserted, by the di'slodgment Vof the'ball 14, through' the bore 10and into the well 4t As -flui'd'is removed vfron'i'the well 4, anequivalent amonnt of fluid 'from within the reservoir closure 21 flowsIfreely through the orifice 23 intothe chamber 5 'and after passingVthrough the bore 6 'restores the normal fluid level within the well 4,but without at any time raising the fluid level within said chamber.

It is obvious that instead of prepared ink and provides vliquid VinkVwithin said well. 'At times'a slightamount of ink from Within said wellcirculates, possibly due to vibration and 'temperature changes,reversely through the bore and in time may color the small amount ofliuid within the chamber 5, but/under no 'condition can it. passupwardlyby or tliroughfthef lair trap ganddiscolor .the water within theclosure2l.

The preferred embodiment ofthis device also compriseslaterallygoppositely extending corrugated supports 315, which provide vpreferablyparallel recesses32 for thezreception and support lof pens, penholdersand pencils', which, -if desi'red5l1nay be of vthe saine orcorresponding color-'to theindicating;

inlays l2 and Thelower '.portionfoii-vsaid stand is alsoprovided' with arecessf, open at lthe bottom, but provided rwithl inwardly directedflanges '34, comprisingecrunways yor supports forthe .'latera'llyopposite portions of afdraw'er 35, suoli as isshown in' Fig. 4.Thelateral'ly oppositewallsl 86` of this drawer are also 1providedwithfelongated slots-37, which slidably receivethelinw ardly project-ingend portions'oli-removable screws 38, .whichv extend preferably inalignment through :the laterally oppositelportions ofthe stand 1. Thisdra-wer may be' of any desired shape and mayicomprise asingleora'multiplicity of conipartments, butin the'present. device it has beenillustrated as comprising ,a central compartment 39 for postage stampsandthe like, laterally' oppositely .and forwardly positioned'compartmentsflO, adapted kto hold solubleinkpellets ot the same-ordifferent colors as may be desire d,A and also comprises laterallyVopp'ositely and rearwardly .positioned compartments 4'1 adapted to holdpeli pointsof the saine ordilferent form, suoliv as ythe so-called stuband Spencerian types.

The drawer may ofcourse be provided with any suitable knob" or handle42. to facilitate its withdrawal from and its return to its operativeposition' within the stand 1.

' From the description of this device, it is also clearly apparent thata pluralityof wells 4'may be employed with. individual bores 6,connecting said` wells with a single auxiliary chamber Vin which apartition repf resented by a.' dot-an'd-'dvash line 43 extends fromthebottoin upwardly `a slight distance above Vthe `uppermost level ofIthe bores'G Vin `that, case. In the operation of the 'device with thisarrangement, there is of course ra single closure 21 for the singlechamber 5 Cil and as water or other fluid flows through the orifice Q3,it thence passes in substantially equal quantities upon opposite sidesof the partition ,413 until the fluid levels upon said opposite sidesrise to the uppermost limit of the respective bores 6. As fluid in theform of ink or the like is withdrawn from each well, just enough fluidfrom within the closure l flows into the chamber 5 to replace the fluidwithdrawn from the latter upon the corresponding side of said partition43.

Having thus described my invention, what I claim and desire to protectby Letters Patent of the United States is l. nn inl-z stand, comprisinga well adapted to hold fluid ink, an air-tight auxiliary chamberconnected with said well by a bore, and a reservoir carried by saidstand and having a lower wall spaced above the fluid level within andclosing said chamber, said wall having a. restricted aperture open atall times to permit the passage of fluid from said reservoir into saidchamber as fluid from Within said chamber flows into said well, saidaperture being sufficiently small to maintain an air trap beneath saidwall and prevent liquid within said reservoir flowing into said chamberfaster than liquid is withdrawn from said well and is replaced by theliquid within said chamber.
